MEDFORD, Ore. - Authorities in Oregon said an arsonist appears to be targeting green Ford Escorts, with three of the vehicles going up in flames during the past month.

Medford police said the most recent incident occurred Sunday, when a 1995 green Escort parked outside of a home was found destroyed after someone broke a window, poured flammable liquid into the car and set it on fire, KTVL-TV, Medford, reported Tuesday.

Police said a 1993 Escort was destroyed in the same fashion Feb. 22. Investigators said a possibly related fire had been set a few days prior to the incident in the laundry room of an apartment building.

The first incident took place Feb. 2, when the owner of a 1992 green Escort found that a container of flammable liquid had been set ablaze next to the tire of her car.

Police said a man in a puffy jacket was spotted riding a mountain bike away from Sunday's fire, but it is not known whether he was involved with the blaze.
